[转载]Windows Security Checklist——Invisible Internet Browsing
文章作者：Larry Stevenson, aka Prince_Serendip, CastleCops Staff WriterNo one application nor technique can protect you at 100%, but you can still get pretty close to that. When these guidelines are followed by Windows users, it can bring their chances of being infected by malwares or attacked by cyberthugs, almost to zero. Now we begin our next installment of the Windows Security Checklist - Part 6: Invisible Internet Browsing.
It is not as complicated as it may first appear, although there is a lot of information to absorb. The Security Experts, 1st Responders, Special Response Team members and Host Consultants at CastleCops can help you, if you have questions about any of these techniques.
Invisible Internet Browsing
Each computer on the Internet is marked with its own special IP-address. (IP stands for Internet Protocol.) For cable users you probably have one or two static addresses that rarely change. For DSL and Dialup users, you may have dynamic ones which change with each logon or fairly often. Dynamic IP's can be traced using Reverse-DNS where the network or ISP you are on allows for it. Each Reverse-DNS address is unique. Even if your dynamic IP-address changes, the Reverse-DNS address will remain the same. For more information contact your network or ISP provider.
Your IP-address allows your ISP and other computers to communicate with your PC. To be completely without an IP-address would be the same as a telephone without a dialtone. There would be no communication, and you would be offline. However, there are ways to mask or encrypt your IP-address.
Proxies are simply servers that connect users to a network. Usually it connects to another network (for example, the Internet) from a local network such as a business or even an ISP (Internet Service Provider). It allows many to access a network with one or several addresses. These servers can be very useful, contributing security, speed and privacy to those who wish to truly enjoy the Internet without giving up their identities.
Tip especially for dialup users: Large downloads can be agonizingly slow on dialup. By connecting to a web proxy server you can speed up the download by having the proxy get the files first and then give them to you at its speed. You may have to test and expirement to find a server that can do that.
By using an anonymous (http) proxy server, you are using their IP instead of your's to access the Internet. An anonymous proxy removes, masks or encrypts your IP on any requests you make when it passes these along to Internet websites. For these proxies to be truly effective it is also important to disable Java, Javascript and cookies in your browser. But, if this detracts from your enjoyment then leave them on. (Be aware though, that by doing so, it is riskier.)
Most modern browsers can be configured for using Proxy Servers. Below are general examples of how the settings are done in a variety of browsers. If your browser is not listed, please consult its Help file.
